I've recently installed Ubuntu 12.10 on a small form factor computer with a dual core Atom 1.86 GHz processor, 2 GB of RAM and a 160 GB SATA HD.
The install was apparently successful (no error messages).
However, on reboot Ubuntu never finishes booting, freezing at various points of what looks like a command line interface:
"Stopping log initial device creation"
"Stopping save kernel messages"
I've tried booting several times, just in case it was a momentary quirk.
I'm not sure what to try next.
